People - Ancient Greece: Erasistratus
Ancient Greek anatomist and royal physician under Seleucus I Nicator of Syria.

Erasistrătus in Harpers Dictionary of Classical Antiquities (Ἐρασίστρατος). A physician of Iulis, in the island of Ceos, and grandson of Aristotle by a daughter of this philosopher. After having frequented the schools of Chrysippus, Metrodorus, and Theophrastus, he passed some time at the court of Seleucus Nicator, where he gained great reputation by discovering the secret malady which preyed upon the young Antiochus, the son of the king, who was in love with his stepmother, Queen StratonicÚ (Appian. Bell. Syr. 59). It was at Alexandria, however, that he principally practised. At last he refused altogether to visit the sick, and devoted himself entirely to the study of anatomy. The branches of this study which are indebted to him for new discoveries are, among others, the doctrine of the functions of the brain and that of the nervous system. He immortalized himself by the discovery of the viae lacteae; and he would seem to have come very near to that of the circulation of the blood. Comparative anatomy furnished him with the means of describing the brain much better than had ever been done before him. He also distinguished and gave names to the auricles of the heart (Galen, De Dogm. Hipp. et Plat. vii.; De Usu Part. viii.; De Administr. Anat. vii.; An Sanguis, etc.). A singular doctrine of Erasistratus is that of the πνεῦμα, or the spiritual substance which, according to him, fills the arteries, which we inhale in respiration, which from the lungs makes its way into the arteries, and then becomes the vital principle of the human system. As long as this spirit moves about in the arteries, and the blood in the veins, man enjoys health; but when, from some cause or other, the veins become contracted, the blood then spreads into the arteries and becomes the source of maladies; it produces fever when it enters into some noble part or into the great artery, and inflammations when it is found in the less noble parts or in the extremities of the arteries. Erasistratus rejected entirely blood-letting, as well as cathartics; he supplied their place with dieting, tepid bathing, vomiting, and exercise. In general, he was attached to simple remedies; he recognized what was subsequently termed idiosyncrasy, or the peculiar constitution of different individuals, which makes the same remedy act differently on different persons. A few fragments of the writings of Erasistratus have been preserved by Galen.

Erasistratus in Wikipedia Erasistratus (Greek: Ἐρασίστρατος; 304 BC- 250 BC) was a Greek anatomist and royal physician under Seleucus I Nicator of Syria. Along with fellow physician Herophilus, he founded a school of anatomy in Alexandria, where they carried out anatomical research. He is credited for his description of the valves of the heart, and he also concluded that the heart was not the center of sensations, but instead it functioned as a pump. Erasistratus was among the first to distinguish between veins and arteries. He believed that the arteries were full of air and that they carried the "animal spirit" (pneuma). He considered atoms to be the essential body element, and he believed they were vitalized by the pneuma that circulated through the nerves. He also thought that the nerves moved a nervous spirit from the brain. He then differentiated between the function of the sensory and motor nerves, and linked them to the brain. He is credited with one of the first in-depth descriptions of the cerebrum and cerebellum. Life Erasistratus is generally supposed to have been born at Ioulis on the island of Ceos,[1] though Stephanus of Byzantium refers to him as a native of Cos;[2] Galen, as a native of Chios;[3] and the emperor Julian, as a native of Samos.[4] Pliny says he was the grandson of Aristotle by his daughter Pythias,[5] but this is not confirmed by any other ancient writer; and according to the Suda, he was the son of Cretoxena, the sister of the physician Medius, and Cleombrotus. From the latter it is not quite clear whether Cleombrotus was his father or his uncle. He was a pupil of Chrysippus of Cnidos,[6] Metrodorus,[7] and apparently Theophrastus.[8] He lived for some time at the court of Seleucus I Nicator, where he acquired great reputation by discovering the disease of Antiochus I Soter, the king's eldest son, probably 294 BC. Seleucus in his old age had lately married Stratonice, the young and beautiful daughter of Demetrius Poliorcetes, and she had already borne him one child.[9] Antiochus fell violently in love with his mother-in-law, but did not disclose his passion, and chose rather to pine away in silence. The physicians were quite unable to discover the cause and nature of his disease, and Erasistratus himself was at a loss at first, till, finding nothing amiss about his body, he began to suspect that it must be his mind which was diseased, and that he might perhaps be in love. This conjecture was confirmed when he observed his skin to be hotter, his colour to be heightened, and his pulse quickened, whenever Stratonice came near him, while none of these symptoms occurred on any other occasion; and accordingly he told Seleucus that his son's disease was incurable, for that he was in love, and that it was impossible that his passion could be gratified; The king wondered what the difficulty could be, and asked who the lady was. "My wife," replied Erasistratus; upon which Seleucus began to persuade him to give her up to his son. The physician asked him if he would do so himself if it were his wife that the prince was in love with. The king protested that he would most gladly; upon which Erasistratus told him that it was indeed his own wife who had inspired his passion, and that he chose rather to die than to disclose his secret. Seleucus was as good as his word, and not only gave up Stratonice, but also resigned to his son several provinces of his empire. This celebrated story is told with variations by many ancient authors,[10] and a similar anecdote has been told of Hippocrates,[11] Galen,[12] Avicenna, and (if the names be not fictitious) Panacius[13] and Acestinus.[14] If this is the anecdote referred to by Pliny,[15] as is probably the case, Erasistratus is said to have received one hundred talents for being the means of restoring the prince to health, which would amount to one of the largest medical fees upon record. Very little more is known of the personal history of Erasistratus: he lived for some time at Alexandria, which was at that time beginning to be a celebrated medical school, and gave up practice in his old age, that he might pursue his anatomical studies without interruption.[16] He and fellow physician Herophilus practiced anatomy with great success, and with such ardour that they are supposed to have dissected criminals alive.[17] Erasistratus appears to have died in Asia Minor, as the Suda mentions that he was buried by mount Mycale in Ionia. The exact date of his death is not known, but he probably lived to a good old age, as, according to Eusebius, he was alive 258 BC, about forty years after the marriage of Antiochus and Stratonice. He had numerous pupils and followers, and a medical school bearing his name continued to exist at Smyrna in Ionia nearly till the time of Strabo, about the beginning of the 1st century.[18] The following are the names of the most celebrated physicians belonging to the sect founded by him: Apoemantes,[19] Apollonius Memphites, Apollophanes[20] Artemidoras, Charidemus, Chrysippus, Heraclides, Hermogenes, Hicesius, Martialis, Menodorus, Ptolemaeus, Strato, Xenophon. An attack on Erasistratus and his followers is preserved in Anonymus Londinensis. Medicine Erasistratus wrote many works on anatomy, practical medicine, and pharmacy, of which only the titles remain, together with a great number of short fragments preserved by Galen, Caelius Aurelianus, and other ancient writers: these, however, are sufficient to enable us to form a reasonable idea of his opinions both as a physician and an anatomist. It is as an anatomist that he is most celebrated, and perhaps there is no one of the ancient physicians that did more to promote that branch of medical science. He appears to have been very near the discovery of the circulation of the blood, for in a passage preserved by Galen[21] he says: The vein[22] arises from the part where the arteries, that are distributed to the whole body, have their origin, and penetrates to the sanguineous [or right] ventricle [of the heart]; and the artery [or pulmonary vein] arises from the part where the veins have their origin, and penetrates to the pneumatic [or left] ventricle of the heart. The description is not very clear, but seems to show that he supposed the venous and arterial systems to be more intimately connected than was generally believed; which is confirmed by another passage in which he is said to have differed from the other ancient anatomists, who supposed the veins to arise from the liver, and the arteries from the heart, and to have contended that the heart was the origin both of the veins and the arteries.[23] With these ideas, it can have been only his belief that the arteries contained air, and not blood, that hindered his anticipating Harvey's celebrated discovery. The tricuspid valves of the heart are generally said to have derived their name from Erasistratus; but this appears to be an oversight, as Galen attributes it not to him, but to one of his followers.[24] He appears to have paid particular attention to the anatomy of the brain, and in a passage out of one of his works preserved by Galen[25] speaks as if he had himself dissected a human brain. Galen says[26] that before Erasistratus had more closely examined into the origin of the nerves, he imagined that they arose from the dura mater and not from the substance of the brain; and that it was not till he was advanced in life that he satisfied himself by actual inspection that such was not the case. According to Rufus of Ephesus, he divided the nerves into those of sensation and those of motion, of which the former he considered to be hollow and to arise from the membranes of the brain, the latter from the substance of the brain itself and of the cerebellum.[27] He asserted that the spleen,[28] the bile,[29] and several other parts of the body,[30] were entirely useless to animals. In the controversy that was carried on among the ancients as to whether fluids when drunk passed through the trachea into the lungs, or through the oesophagus into the stomach, Erasistratus maintained the latter opinion.[31] He is also supposed to have been the first person who added to the word arteria, which had hitherto designated the canal leading from the mouth to the lungs, the epithet tracheia, to distinguish it from the arteries, and hence to have been the originator of the modern name trachea. He attributed the sensation of hunger to emptiness of the stomach, and said that the Scythians were accustomed to tie a belt tightly round their middle, to enable them to abstain from food for a longer time without suffering inconvenience.[32] The pneuma (spiritual substance) played a very important part both in his system of physiology and pathology: he supposed it to enter the lungs by the trachea, thence to pass by the pulmonary veins into the heart, and thence to be diffused throughout the whole body by means of the arteries;[33] that the use of respiration was to fill the arteries with air;[34] and that the pulsation of the arteries was caused by the movements of the pneuma. He accounted for diseases in the same way, and supposed that as long as the pneuma continued to fill the arteries and the blood was confined to the veins, the individual was in good health; but that when the blood from some cause or other got forced into the arteries, inflammation and fever was the consequence.[35] Of his method of cure the most remarkable peculiarity was his aversion to bloodletting and purgative medicines: he seems to have relied chiefly on diet and regimen, bathing, exercise, friction, and the most simple vegetables. In surgery he was celebrated for the invention of a catheter that bore his name, and which was S-shaped.[36]
